Jennifer Neal and her sister Stacy Fingers haven’t been able to sleep much. Not since their sister, Jamie — Stacy’s twin — was last heard from a month ago in Peru. “She’s my sister. I’m just not gonna listen to anybody until she calls me,” Jennifer said, as a tear rolled down her cheek. Jamie’s twin’s biggest fear: “That she’s not safe,” Stacy said. “We’re all three pretty close. We’ve all three really had each other for a long time,” Jennifer added.
